Apparently the Solaris version of ZFS does support losing the ZIL. So can somebody confirm what happens in FreeBSD 8.1 (ZFS v14)? Here's the forum post: *If you are going to split the ZIL onto a separate device, then you ***MUST* ** make it a mirrored vdev. If the ZIL device ever dies, the entire pool goes with it!! ZFSv13 (in FreeBSD 8) doesn't support the removal of ZIL devices.* http://forums.freebsd.org/showthread.php?t=9859 Thanks for your responses. --Gil Vidals / VMRacks.com
